Jason Michael, their tights ends coach, is following Whisenhunt to Tennessee, the Titans announced Friday. It's a good promotion for Michael, who will serve as offensive coordinator after working as San Diego's tight ends coach since 2011.

On Wednesday, the Titans requested and were granted permission to interview Michael. Given he and Whisenhunt were colleagues the past season, the interview was considered all but a formality.

Last year, the Chargers lost all but two coaches on their offensive staff — Michael and running backs coach Ollie Wilson. This year, with Whisenhunt and Michael, they've lost two. McCoy will likely use next week's Senior Bowl in Mobile, Ala., to finalize his hires.

Whisenhunt is expected to handle the Titans' play-calling duties as head coach.
